During muscle development, nuclei travel from the centre of the myofibre to the periphery, a process defective in certain diseases. A new study reveals that this movement is due to centripetal forces ...

Skeletal muscles are built from small contractile units, the sarcomeres. They are connected in a well-ordered series to form myofibrils that span the entire muscle. Contractions of these sarcomeres ...

Myosin was localized in situ in the posthatch chicken pectoralis using isoform-specific mAbs. The distribution among myofibrils was demonstrated by immunofluorescence and by immunogold EM. Fluorescein ...

How the bicep tenses is no longer a secret. In every muscle cell there are so-called myofibrils, which contract at the same time. They are responsible for muscle movement. Each of these fibrils ...

Researchers at the University of Liège, Eric Parmentier and Marc Thiry have just made the unexpected discovery of a novel organisation of muscle fibres in Parophidion vassali, a fish that lives in the ...

Many patients with heart disease face limited treatment options. Fortunately, stem cell biology has enabled researchers to produce large numbers of cardiomyocytes, which may be used in drug screens ...

(PhysOrg.com) -- Cellular engineers at the University of Pennsylvania have determined that cardiomyocytes, the specialized cells that form the heart muscle, thrive when cultured in an environment that ...

In a recent clash against the Melbourne Storm, the Brisbane Broncos endured a nightmare rarely seen in professional sport—three players tore their hamstrings in a single game. Two players, Adam ...

In order to move the body, skeletal muscles are pulling on the skeleton. For efficient muscle and skeletal movements it is essential that the muscle contracts only along a defined axis, for instance ...
